Abstract

Power transmission and coupling of coupled waveguide fibers are affected on coupling coefficient. The coupling coefficients obtained in experimental result vary in a wide range. It has a function of separation of fiber axis and refractive index of core and cladding. For empirical formula, coupling coefficient is calculated from experimental result of coupling ratio distribution from 1% until 75%. Theoretically, it has a dependence of some parameters resulting sinusoidal curve. Both empirical and theoretical formulae are compared to obtain new phenomena of refractive index of fibers after fusion.
